In an interview to Sport CZ website the outspoken Czech player Barbora Strycova spoke about Serena Williams's behaviour during the US Open final towards the umpire Carlos Ramos.

The world No. 25 believes that the Portoguese just did his job. 'Ramos is tough, one of the best umpires in the world. He did what he had to do in that match, because she overcame the limit. Did she have to behave differently only because she was Serena Williams? I find it interesting that she did it only when she was losing', said Strycova.

Serena said umpires treat women differently than men, but Strycova does not agree with it: 'This is a bullshit. For umpires being women or men doesn't matter. In comparison, I never saw (Rafael) Nadal shouting like that with an umpire.
